Description

The STM Tuned fuel pressure regulator kit is designed for the 2003-2006 Mitsubishi Evolution VIII and IX models. This kit provides all necessary fittings, hardware, and lines to connect from the factory-style fuel rail outlet to the Fuelab regulator and back to the OEM return line. It features a direct-fit mounting bracket for easy installation to the firewall and a direct-fit fuel rail fitting.

The kit includes a soft nylon braided hose, which is safer for surrounding components than stainless steel. The Fuelab mini regulator is E85 safe and available in multiple color options. Miscellaneous clamps, zipties, and stainless bolts are also included to simplify installation.
